All Stainless steel case, with integrated bracelet. Bracelet has two parts; a banded steel mesh on either side of the watch case, and an scissor-type expansion portion connecting them at the back. The bracelet ends fit into a cutout in the case, and is sandwhiched between the front bezel and the caseback. Caseback is screw-on.

Problem is, it doesn't have a rotating bezel, or any indication of waterprotection. So while the case may well be similar to that used for the Oceanographer, you'll have a hard time convincing me that mine is an Oceanographer. That said, if you're confident that all Clipper submodels of this era had a two-piece caseback, I'll accept that it isn't a Clipper either. Alas, that puts us back at square one; what IS it? Possibly some un-named variant composed of excess Oceanographer case stock?
